`IOSEPII TTU BERTRAND, OF ISLE VERTE, QUEBEC, CANADA.

MARINE CONCRETE CONSTRUCTION.

To all 'whom it may concern:

Be it known that I, JOSEPH TETU BER- TRAND, a subject of the King of Great Britain, residing at Isle Verte, in the county of Temiscouta, Province of Quebec, Canada, have invented certain new and useful Improvements in Marine Concrete Construction and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to marine concrete construction.

The object of my invention is to provide a construction from interlocking blocks adapted to be secured to the exposed face of a temporary submerged or partially submerged structure such as a wharf, piles etc.

Y A more specific object is to provide blocks ofa form adapted to easily interlock with each other, to form a water tight joint, and the bottom block of which may be secured to a supporting beam and present an inclined surface on-its exposed face.

A further more specific object is to provide a simple means for guiding the blocks to their interlocked positions, which means may be easily removable to permit the insertion of a tie rod or grouting.

M invention consists of the construction, combination and arrangement of parts and the particular form of block, as herein illus' trated, described and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a vertical section through a temporary structure, showing the method of applying the blocks thereon, some of the b ocks being shown in vertical section and the two bottom courses in end elevation; Fig. 2 is a front elevation partly broken away showing the application of the invention, to a temporary structure; and Fig. 3 is a horizontal section through the sheathing of a wharf showing the application of the invention thereto and also showing in plan the application of the invention to piles.

Referring to the drawings, 1 designates a temporary structure which may be a wharf or piles. Guide strips 2 are driven parallel to the outer face of the wharf or pile and secured thereto in any suitable way, or if Speccaton of Letters Patent.

Serial No. 383,395.

they can be firmly held otherwise they need not be necessarily secured to the temporary structure. The guide strips 2 are provided with enlarged outer edges 3.

The blocks used in the construction are designated as a whole by the numeral 4 and are provided with longitudinal mortises 5 in their upper faces, which mortises have in afford a .greater resistance to the action of the water into which it is submerged. The bottom block 9 is further provided with a longitudinal mortise 11 in its under face adapted to receive a foundation beam 12 which extends longitudinally of the shelf formed by the blocks. Thisbeam-12 is secured by bolts 13 to the bottom block 9.

Each of the blocks 4 is provided with a plurality of openings 14 arranged centrally thereof and extending through the tenon 6' and into the mortises 5. Disposed through the openings 14 is a tubular member 15, which may be screwthreaded into the beam 12, so that it may be readily removed. The function of the tubular member 15 is twofold: 1st., it serves as a guiding means to cause the blocks to interlock with each other as they are placed in position. 2nd,-it serves as a casing for a locking rod or chain 16 which is disposed therethrough and has its lower end secured to the beam 12.v

In placin the blocks in position, the rst lock 9 may be placed on the beam 12 when the latter is floating on the surface of the water. The other blocksmay be successively placed thereon and guided into position by means of the tubular guide member 15, until the entire shell is submerged, to the proper depth and settles into lace. p The blocks 4 are provided with mortises 17 arranged vertically in their inner' faces and adapted to receive the .enlarged outer edges 3 of the guide strips 2 so that the structure is locked to the temporary structure 1, leaving a space between the outer face of the temporary structure and the inner face of the shell formed by the blocks 4. The particular form of locking means between the temporary structure 1 and the blocks 4 permits the entire structure settling iirmly on its foundation. After the shell formed by the blocks 4 is in osition a suitable iilling 18 may be placed3 between the inner face of the shell and the outer face of the temporary structure 1. This 'Iilling may be of sand, silt or other suitable material.

After the structure is completed the tubular member 15 may be removed and the openings 14 iilled with grouting around the member 16,'01 both the members 15 and 16 may be removed and be replaced by heavier tie rods.

Owing to the particular form of the blocks 4 cement is not necessary for joining the courses, but in practice I use a coating of paint or similar material, to insure greater tightness of the joint.

I-Iaving thus fully described my invention,

f what I claim as new and desire to secure by Letters Patent is:

1. In combination with a temporary marine structure a plurality of courses of interlocking blocks disposed parallel to the face of the structure, and means for guiding the blocks to their interlocked position.

2. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure and removable means for guiding the blocks to their interloclred position.

3. In combination with'a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, means for guiding the blocks to their interloclred position, and means for locking the courses to the temporary structure.

4. In combination with a temporary' marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, means for guiding the blocks to their interlocked position, and vertically disposed guide strips carried by the temporary structure and interlocked with the inner faces of the blocks.

5. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure and having vertical mortises in their inner faces, means for guiding the blocks to their interlocking position, and vertically disposed guide strips carried by the temporary structure and provided with enlar ed outer edges arranged in the mortises in t e blocks.

6. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, means for guiding the blocks to their intel-locked position, and means for supporting the bottom course of the blocks.

7. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, the bottom course of which blocks is provided with a longitudinal mortise and an inclined outer face, a beam disosed in the mortise, means for guiding the locks of each course to their interloclred position, and a connecting member secured to the beam and extending vertically through all of the courses.

8. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, means for guiding the blocks to their interlocked position, and a locking member disposed through the guiding means.

9. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, and a tubular member disposed vertically through the blocks.

10. In combination with a temporary marine structure, a plurality of courses of interlocking blocks disposed parallel to the face of the structure, means for guiding the blocks to their interlocked position, and a filling disposed between the inner face of the courses and the outer face of the temporary structure.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.
